[单项选择]Questions 21-25 are based on the following passage:
Wood carving refers to the art of creating or decorating objects of wood by carving with a sharp, hand-held tool. This form of art has a history of over 1,000 years and a unique artistic style. The following is some introduction about wood carving in America.
Wood carving began as a necessity in America and developed into an art. Because of the lack of other materials, early settlers were forced to make tools and utensils out of wood. At first, these articles were whittled with a knife, but when pioneer craftsmen set up their primitive shops most of them were fashioned on a lathe--a machine which holds an object and rotates it while it is being shaped by a tool.
However, even after Massachusetts-born Thomas Blancard designed a lathe which could turn irregular shapes--an innovation that made possible mass production of gunstocks, shoe lasts, oblong and square wooden wares--craftsmen who could use knife and chisel

A New Strategy to Overcome Breast Cancer
Post-menopausal（绝经后的）women who walk for an hour a day can cut their chance of breast cancer significantly,a study has suggested.The report,which followed 73,000 women for 17 years,found walking for at least seven hours a week lowered the risk of the disease.The American Cancer Society team said this was the first time reduced risk was specifically linked to walking.UK experts said it was more evidence that lifestyle influenced cancer risk.
A recent poll for the charity Ramblers found a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers.This study,,published in Cancer Epidemiology,Biomarkers&Prevention,followed 73,615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group.
They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking , swimming and aerobics（有氧运动）and how much time they spent sitting,watching television or reading.They completed the same questionnaires at, two-year intervals between 1997 and 2009.Of the women,47%said walking was their only recreational activity.Those who walked for at least seven hours per week had a 14%lower risk of breast cancer compared to those who walked three or fewer hours per week.
Dr.Alpa Patel,a senior epidemiologist at the American Cancer Society in Atianta Georgia,who led the study,said:"Given that more than 60% of women report some daily walking,promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women.We were pleased to find that without any other recreational activity,just walking one hour a day was associated with a lower risk of breast cancer in these women." " More strenuous（紧张的） and longer activities lowered the risk even more."
Baroness Delyth Morgan,chief executive of Breast Cancer Campaign,said:"This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporated into our normal day-to-day activity can make a difference."
She added:"We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place.The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer."
Dr.Alpa Patel was______.
A.chief editor of Cancer Epidemiology
B.chair of the American Cancer Society
C.chief executive of Breast Cancer Campaign
